bought brand new cartridges for my printer from the HP Canada website and they didn't work upon receiving them. I called the company for technical support and the tech immediately confirmed they were faulty so put me thru to sales to refund my purchase however as soon as I explained it to them they said this is a technical issue and put me back to tech support. I then held for 47 minutes before an automated voice said plz call again and hung me up! their customer service and their products are TERRRRRRRIBLE!
